Vivaldi
 
A few weeks ago I came across the Vivaldi browser, or at least came across it again. I had first seen it several years ago and failed to find anything interesting in it. Chromium-based, it seemed to have so many options that it appeared like hard work.
Earlier this month the Vivaldi team introduced the finished version of Vivaldi Mail and Calendar. I checked them out and, to my surprise and delight, they worked very well. I ran them alongside Mailbird for ten days and now I can announce to an uncaring world that I have switched completely to Vivaldi.
One big advantage: it works happily with WebDav, so I can run my calendars from my own website, and no longer go through Google.
